In a display apparatus and a driving method thereof, image data corresponding to plural different positions of a display panel are added to each other, and a sum of the image data of a present frame is compared with a sum of the image data of a previous frame to determine whether an image displayed on the display panel is a still image or not. While a still image is displayed, brightness of the display panel is gradually lowered. Accordingly, the display panel may prevent occurrence of afterimages and deterioration of organic electroluminescent light emitting devices, as well as reduce power consumption.

An array substrate includes a base substrate, a plurality of gate lines, a plurality of data lines and a pixel matrix. The plurality of gate lines and the plurality of data lines define pixel areas. The pixel matrix is formed on each pixel area, and includes a plurality of pixel columns and pixel rows. Each pixel column has a first pixel group and a second pixel group. The first pixel group is electrically connected to a first gate line adjacent to the pixel column. The second pixel group is electrically connected to a second gate line adjacent to the pixel column. Each pixel row is electrically connected to one data line adjacent to the pixel column.

A display device includes a data driver, an inverter, a display panel, and an intercept unit. The data driver provides an image signal and the scan driver generates a control signal corresponding to the image signal. The inverter provides an inverted control signal. The display panel has a PMOS transistor that provides the image signal to a pixel electrode based on the inverted control signal. The interception unit intercepts an abnormal signal that is forwarded to the PMOS transistor. Therefore, a signal having an abnormal voltage level may be interrupted to prevent display defects resulting from the abnormal voltage level.
